The test suite fails only with Quantum enabled.

Though in my devstack environment it fails with a different stack trace :
Details: {"itemNotFound": {"message": "Fixed IP 10.0.0.4 not found", "code": 404}}

[Jordan Pittier (jordan-pittier)]

These tests make use of nova/api/openstack/compute/contrib/fixed_ips.py. But this file is not "Quantum aware" at all. Moreover the method get_fixed_ip from nova/network/quantumv2/api.py that might be called for these tests is flagged as "NotImplemented".

A possible fix would be to use network.API().get_fixed_ip_by_address() with Quantum and network.API().get_fixed_ip() without Quantum. But that's not elegant at all.

Guys I'm not sure this has something to do with Quantum.
In fact I don't know if quantum implements those functionalities, but the problem pointed in the review link is related to postgresql and fixed by this patch I've made https://review.openstack.org/#/c/30057/

You can check this looking into n-api logs of the pointed run

Look for:
2013-05-20 16:36:06.461 9540 TRACE nova.api.openstack DataError: (DataError) invalid input syntax for type inet: "my.invalid.ip"

If I'm right this is a duplicate of bug #1182754
